AS/NZS 3582.1, AS 3582.2 and AS/NZS 3582.3 are now available for purchase through SAI Global from Friday, 12 February 2016.   

AS/NZS 3582.1 Supplementary cementitious materials Part 1:  Fly ash was prepared by the Joint Standards Australia/Standards New Zealand Committee BD-031, Supplementary Cementitious Materials, to supersede AS 3582.1—1998, Supplementary cementitious materials for use with portland and blended cement, Part 1: Fly ash. Commencing back in 2014 following consultation with members, stakeholders in both countries, Standards Australia and Standards New Zealand decided to develop this Standard as an Joint Standard.

The objective of this Standard is to set out the requirements for fly ash for use as a cementitious material in concrete, mortar and related applications. The principal differences between this and the previous edition are the introduction of new grades of fly ash, recognition of proven and unproven sources, amendments to sampling and testing requirements. The Standard now aligns with AS 2758 in terms of requirements for mitigating alkali silica reaction in concrete. It also aligns with AS3972. 

The term ‘informative’ has been used in this Standard to define the application of the appendix to which it applies. An ‘informative’ appendix is only for information and guidance. Notes used in this Standard are of an advisory nature only and are used to give explanation or guidance to the user on recommended considerations or technical procedures, or to provide an informative cross-reference to other documents or publications. Notes to clauses in this Standard do not form a mandatory part for compliance with this Standard.

AS/NZS 3582.1 Supplementary cementitious materials Part 1:  Fly ash can be purchased online at SAI Global.
